[1] Her thesis was titled The impact of urbanisation and industrialisation in medieval and post-medieval Britain: an assessment of the morbidity and mortality of non-adult skeletons from the cemeteries of two urban and two rural sites in England (AD 850–1859) supervised by Charlotte Roberts.
[5] Along with Reading University colleagues Gundula Müldner and Hella Eckardt, Lewis took part a research project to examine the archaeological evidence for immigration in Roman Britain and how these people interacted.
The project, which began in 2007, was funded by the Arts and Humanities Research Council (£337,000)[4] and the results were used to inform displays at the Yorkshire Museum and create educational resources for Key Stage 2 pupils.
The AHRC provided additional funding (62,000) while the Runnymede Trust also supported the project to help the website addressed what children wanted to learn about.
